属性

主要特点与优势

Rapid Deaeration: Accelerates the release of entrained air, preventing structural defects in coatings and specialized adhesives.
Superior Stability: Maintains chemical integrity and performance in extreme pH (3–12) and fluctuating high-temperature industrial environments.
High Efficiency: Effective at exceptionally low inclusion levels (0.1–0.5%), significantly reducing overall operational costs and inventory needs.
Excellent Compatibility: Integrates seamlessly into resin systems and surfactant-rich formulations without causing surface craters or fish-eyes.
Extreme Durability: Provides persistent foam inhibition over extended processing times, even under the most rigorous high-shear mechanical agitation.
Process Safety: Non-toxic and environmentally compliant chemical profile designed for secure handling by plant operators and staff.

规格

技术亮点

Chemical Identity: Advanced organosilicon emulsion utilizing high-purity Polyether-modified Polydimethylsiloxane (CAS: 63148-62-9 / 9003-11-6 blend).
Active Content: Optimized concentration ranging from 30% to 50% for maximum potency in demanding applications.
Physical Appearance: Milky white, low-viscosity liquid designed for precise metering and rapid, uniform dispersion.
Ionic Character: Versatile non-ionic nature, ensuring maximum flexibility in cationic, anionic, or non-ionic aqueous systems.
Standard Viscosity: Calibrated between 500–2000 mPa·s at 25°C for optimal flow and bulk handling.
Water Dispersibility: Readily dilutable for exact dosing in continuous or batch production processes.
Surface Tension: Significantly reduces equilibrium surface tension levels to enable instantaneous rupture of stable bubbles.

实际行业应用

应用领域

Textile Processing: Controls foam during high-temperature dyeing and scouring operations to prevent fabric spotting and uneven coloration.
Industrial Cleaning: Essential in high-pressure spray cleaners and metalworking fluids where intense agitation generates excessive, problematic foam.
Wastewater Treatment: Effective in biological plants and cooling towers to prevent vessel overflow and maintain system throughput.
Paints and Coatings: Eliminates micro-foam during grinding and application, ensuring smooth, defect-free, high-gloss surface finishes.
Adhesives and Sealants: Prevents air entrapment during packaging, maintaining bond strength and consistent product density.
Agricultural Chemicals: Enhances the spray efficacy of pesticides and fertilizers during tank mixing and field-based application for optimal coverage.
